Baby anatomy

Did anyone experience having trouble with getting a certain view of the baby throughout their pregnancy? It started with the anatomy scan, they couldn’t see the right side of her heart and a few other things. They checked again at 24w and 28w, and still not able to see the right side of heart but able to see the other things. Each time they reassured me that it was just positioning, the way baby is scrunched up and positioned but after they couldn’t see at 28 weeks, my OB told me she would feel more comfortable with me delivering at another hospital with a higher level Nicu just in case. She said not because she thinks something is wrong, but to be safe. I’m 32 weeks and they are going to try again but I’m getting really worried that something is wrong as i thought they would’ve it been able to view it by now 😢
